Answer:
It refracts when it hits the glass.
The light must be either very dim or else non-existent.
We can't see the light wave or the label.
UV Radiation since it has a higher frequency than the others. The higher the frequency the shorter the wavelength.
Answer:
Explanation:

Answer:
Height.
Explanation:
Potential energy can be defined as an energy possessed by an object or body due to its position.
Mathematically, potential energy is given by the formula;

Where,
P.E represents potential energy measured in Joules.
m represents the mass of an object.
g represents acceleration due to gravity measured in meters per seconds square.
h represents the height measured in meters.
Hence, the property of the object (having a mass of 5 kilograms) which must differ to have different gravitational potential energies is the height from which they are falling from.
The object having the higher height would have a greater gravitational potential energy than the lower object.
